Plastic covered cable-good idea! I used 2 sections of a cleaning rod chucked to a drill, attached and pushed through a .30 cal brass bore brush. With the brush in the reciever I spun steel wool around the brush then pushed/pulled this into the chamber that had been carefully swabbed with rust/blue removal solvent. Ran the drill at low speed, cleaned with hot water and soap, then a normal cleaning finished up with a little light coat of gun oil in the chamber.
The fired cases that would not load into the chamber now load and extract, so it seems to have worked to this point. The next trip to the range will tell but my feeling is that I will need to have the chamber reamed out.
This M1 is an International Harvester and the barrel is marked with several "P"s and ordinance stamps, and what looks like a 1956 date. Bolt is HRA and trigger and op rod are stamped SA. So barreled receiver looks original (?) and the other parts traded in for upgrades.
